VALVE.

SPECFICATION forming part of Letters Patent No. 397,134, dated ebruary5, 1889.

I Application filed August 3l, 1888.

` opening', ll, which is adapted to align with To all whom it 71mg/con/cern:

Be it known that I, GEORGE ADELBERT MATTESON, a citizen of the UnitedStates, residing' at Cridersville, in the county of Auglaize and Stateof Ohio, have invented new and useful Improvement-s in Valves, of whichthe following is a specification.

rlhe object of my invention is to provide a combined stop-cock,clieclovalve, and connec-` tion or union for steam, fluid, or gas lines,whereby the inconvenience of separately connecting the stop-cock and thecheek-valve to the line may be avoided.

A further object of the invention is to provide means whereby thecheck-valve may be removed at any time to repair or clean.

lith these objects in view the invention consists in a cert-ain novelconstruction and combination of devices, fully described hereinafter, inconnection with the accompanying drawings, and specifically pointed outin the appended claims.

In the drawings, Figure l is a side view of a stop embodying myimprovements. Fig. 2 is a central longitudinal sectional view of thesame. Fig. il is a central transverse sectional view with the valveopen. Fig. l is a similar view with the valve closed. Fig. 5 is a de`tail perspective view of the check-valve with its removable seat. Fig. 6is an end view, partly in section, of the casing.

Referring by letter to the drawings, A designates the casing of thestop-cock having the transverse bore a., and the upper end of the casingis provided with the horizontal flange B, to which is adapted to bebolted a pla-te, C, having a rigid nut, c. This nut is screwed on thelower end of a section of the line-pipe D. It will be seen that thisplate and nut form the connection or union between the line-pipe and thestop cock. The under side of the plate O is provided with a dependingrib, E, which iits in an annular groove, e, in the upkper side of theflange B, and bears on a packing-ring, F, which is located in thegroove.

The core G of the stop-cock is conical in form, fits in the bore a inthe usual way, and is held in place by a suitable nut, g, which isscrewed on the smaller end of the core. The core is provided with atransverse elongated Serial No.284,272. (No model.)

I the vertical opening in the casing to allow the passage of the steam,fluid, or gas.

I represents a recess, which is formed in the side of the core G, inwhich is arranged the valve-seat K, having an opening, k, therein, whichregisters with the opening H in the core, and on the outer side of thisseat is hinged the check-valveL, which is thus received completelywithin the recess in the core. When the stop-cock is open, this eheckvalve hangs loosely, thereby leaving' its seat l and allowingI thepassage 0f the steam, ilnid,

or gas; but the lower edge of the said valve projects slightly into thevertical opening of the casing, whereby, if the pressure is too Violent,the valve will be partially or entirely closed. Then the stop cock isclosed, the check-valve is turned around on the upper side of the core,and its lower edge, or a rib, l, on its out-er side, bears against theside of the bore a and holds the check-valve tightly in place. Theobject of this rib is to prevent the entire side or lower edge of thecheckvalve from bearingv against the side of the bore, since in case thelatter should become corroded or rusted, the rib would not be as liableto cling to the side of the bore and prevent the operation of thestop-cock as if a larger surface were in contact therewith.

The manner of hing-ing the check-valve is as follows: lt is provided atits ends with the trunnions L L', which are mounted in bearings R R inthe sides of the recess I. One of these bearings is open at one side, toenable the valve to be removed from the easing. lVhen the stop-cock isclosed, the transverse opening H therein assumes an approximatelyhorizontal position,(out of alignment with the opening in the casing)with its open end adjacent to the side of the casing; and therefore toallow a perfect draining of the stop-cock and check-valve, when in thisposition, l provide a vent, M, in the side of the casing in suchposition as to allow the escape of any accumulation.

It will be readily seen that having combined the check-valve with thestop-cock it is only necessary to make one connection, instead of more,and therefore time is savedv in IOO putting,l the device in place, inliddition to the time, material, and expense which are saved ill theoollstruetion thereof.
